摘要： In the present arrangement, a forest machine is controlled, which forest machine includes a body (2), a boom (3) in connection with the body (2) and a tool (4) at the end of the boom (3). A sensor (9) arrangement determines in advance the size of utilisable free space (11A, 11B) starting from the end of the boom (3). This determination consists of determining a direction and a length of the free space (11B). The operation of the tool (4) is allowed into the direction and for the length of the utilisable free space (11A, 11B) determined in advance.

摘要： A cutting device includes a generally planar guide bar having a peripheral groove. An endless saw chain is disposed around the guide bar and includes links and connector elements joining the links to each other to form an endless chain loop. The links include drive links and consecutive tooth links connected to a same one of the drive links. Each tooth link includes a cutting tooth protruding from one side of the saw chain. Consecutive cutting teeth of the tooth links are arranged to alternate to right and left sides relative to a plane defined by the guide bar. The saw chain is operably circulated around the guide bar groove for cutting.

摘要： A timber-working device has a frame, including a feed axis having first and second sides. A drive system independently feeds stems along the feed axis, and has a first rotary drive having a first wheel acting against a first stem on the first side, and a second rotary drive having a second wheel acting against a second stem on the second side. The device has at least two distance measurement devices, each side of the feed axis having an associated distance measurement device. Each generates measurement signals indicative of the length of stems fed along the feed axis, at least one of them indicative of rotation of one of the rotary drives. A processor receives the respective measurement signals, and for each of the first and second stems, determines the length of at least a portion of the stem fed by the drive system based at least in part on the respective measurement signals.

摘要： A timber-working device comprises a frame having a feed axis and a drive system configured to feed at least one stem along the feed axis. The drive system comprises a first drive arm pivotally attached to the frame on a first side of the feed axis, having a first rotary drive having a first wheel. A second drive arm is also pivotally attached to the frame on a second side of the feed axis, having a second rotary drive having a second wheel. The drive system also comprises a third rotary drive having a third wheel, and a fourth rotary drive having a fourth wheel, mounted on the frame on the first and second sides of the feed axis respectively. At least one processor controls operation of the rotary drives, such that in a first mode the speed of the respective wheels of the rotary drives on the same side of the feed axis is substantially the same, and in a second mode the speed of the respective wheels of at least two rotary drives on opposing sides is substantially the same.
